Star Trek / Green Lantern #2

Synopsis

The reactivated rings find new hosts: the yellow ring chooses Klingon General Chang, the blue ring chooses Chekov, the violet ring choose Uhura, and the indigo ring chooses McCoy. The red ring travels to the home planet of the Gorn to choose a host, and the orange ring travels to Romulus and chooses Praetor Decius. Hal and the Enterprise crew stop Chang's yellow-powered attack, but Chang returns to Qo'nos and kills the Klingon council. As he is about to seize control of the Klingon empire, Sinestro shows up to confront him.
